Connor Parsons and Dean McMenamy were also on target for Waterford with Harps having defender Daithi McCallion sent off in the second half of their heaviest home loss of the season.
In March, Waterford put seven past Harps at the RSC and the scoreline here could have matched that were it not for a couple of big saves from home goalkeeper Tim Hiemer and a few spurned chances from the visitors.
While the evening unravelled for Dave Rogers' Harps after McCallion's dismissal in the 57th minute, Waterford were already well on their way to maximum points by that point.
Five minutes later, Waterford doubled their lead. Coughlan got too much time inside the area and the former Sligo Rovers and St Patrick's Athletic attacker delightfully curled beyond Hiemer to the bottom corner.
Earlier, Barry Baggley was inches from opening the scoring, but his strike from distance rattled the underside of the crossbar before landing in the hands of the grateful Hiemer. It was one of those instances where, in the sport's more loftier stages, the opinion of VAR may well have been called for.
Waterford's quick-fire goals rocked Harps back on their heels and the hosts were under siege in the closing chapter of the opening period.
Hiemer was forced to claw over from a Shane Griffin header while McMonagle took the ball from the toe of Parsons, albeit at the expense of a corner, with the Waterford frontman looking set to apply the finish.
Michael Harris had started in place of Filip Da Silva but, the Convoy man having picked up a cut late in the first half, they switched at half-time.
Harps could have pulled one back eight minutes into the second half, but Sean O'Donnell was narrowly wide when he got his head on the end of Caoimhin Porter's cross.
With Harps down to ten men after McCallion saw red, McMenamy's stunning strike from long range gave Hiemer no chance just after the hour.
With his first touch, sub Christopher Clarke had a chance to add a fifth, but McMonagle got a vital touch to thwart his efforts.
Seven minutes from the end, Hiemer spared further woe as he turned around the post from Coughlan.
